hi! i had a contract with AT&T that ended in may and i switched over to verizon and bought the lg voyager which i really liked but thought it was maybe a little to big so i traded it in for the lg chocolate within the 30 day trading period. but now i really wanna get a new phone like maybe the EnV 2 or the lg dare. if i bought the new phone off ebay or amazon or another website how would i get verizon to activate it, without having to pay for a 2 year contract since i just want to change phones not get a new contract?
and am i allowed to change phones even though ive already changed them once (lg voyager to the lg chocolate)?
thanks!

Yea you can. Just buy the phone, call Verizon, and tell them you want to do an ESN change. I do it all the time. They're going to ask you for some serial numbers that are under the battery of the new phone. They then just change the same service to the new phone and disconnect the old one.
